COP HOLDER FOB TEXTILE MACHINES.

Application filed October 17, 1925; Serial No. 63,005.

This invention relates to cop-holders for use'on creels, winding machines or other textile apparatus, and particularly to a copolder for supporting cones of yarn, thread and the like.

A principal object of the invention is to provide a device of the type specified for gripping the interior of the tube on which the'cone, cop or other package is wound to secure it rotatively .with and longitudinally of the spindle which serves as its support.

Another object of the'i'nvention is to provide a device of the type specified which will act automatically to grip the tube when the latter is pushed onto the spindle without requiring the operation of levers, dogs, or other mechanical gripping or expansionmeans. Another object of the invention is to pro.- videa device of the type. specified which will hold the cop-tube firmly and securely in place on the spindle without danger of its accidental release, but which will release the tube to allow its manual removal when a .7 2 6 strong pull is exerted thereon.

.45 employed for. attaching the gripping-means Anotherobject of the invention is to provide a device of the type specified which is proof against derangement or getting out of order and durable in useover long periods '30 without excessive wear or deterioration.

. Another object of the invention is to provide a device of the type specified which is simple and convenient to construct and economical in its cost of manufacture.

Further objects of the improvement are set forth in the following specification which describes a preferred embodiment .of the invention as illustrated in the accompanying drawings. In the drawings:

Fig. 1 is a viewshowing my improved cop-. or cone-holder as applied to use, and ilpart of or attached to the creel frame, and fastened in place by a set-screw 4;.-

On the outer end of the' spindle 2 I preferably place .a hub or collar 5 fastened there to by a set-screw 6 and having its forward rim beveled off at 7. Positioned rearwardly from the collar-5 is a sleeve or bushing 10 secured to, the spindle 2 by suitable means,

such as the set-screw 11. The sleeve-10' is provided with an annulus or flange 12 against the face of whichis held the resilient gripping-element 15 for securing the coptube in position on the spindle 2.

' In accordance with-the pretent improvenientthe gripping-means for the cop-tube.

takes the form of a concavo-convex disk or slip over the threaded portion 17 of the 7 sleeve 10 to seat it against the flange- 11. A washer 18 is then placed against the forward side of the rubber disk 15 and a nut 19 screwed onto the sleeve 10 to bind the disk between the flange 11 and-washer 18.

Normally, the rubber disk or washer 15 is only slightly concave'd on its rearward side as illustrated by the dash lines in Fig. 1, but when the cop-tube C is slid on to the spindle 2 it will flex the disk 15 to convex it to a greater degree, as illustrated by the full lines in Fig. 1, whereby its rim will be caused to bind tightly against the interior of the cop-tube to frlctionally grip the latter. As

the tube C is pushed onto the spindle 2 its lustrating the gripping-means thereof inflsec- The tube C is usually made of paper pulp,

tion taken irkanaxial plafie F1g.2 is alt-perspective view of the sleeve to the spindle; and I Fig. 3 is a perspective view of the resilient gripping-means.

Referring to Fig. 1 of the drawings, 2 designates a rod or shaft which may constitute the rotating s indle of a winding machine or other textll'e apparatus, or the fixed spindle or skewer of a'creel or supplystand. In the latter case the rod or spindle fiber or similar material and itsinn'er'sur face is somewhat rough. Therefore, the edge of the resilient disk 15 will grip the interior of the tube very firmly and securely and prevent its withdrawal from the spindle 2under ordina conditions. That is to say, I the tube 0 will e held by the frictional grip of the disk 15 to secure it rotatively with and longitudinally of the spindle 2 as the latter is' operated to wind yarn or thread 'on the tube in the form of a cone or package as indicated by dash lines in Fig. 1. When 55' 2 may be heldin a hub or boss-3, forming a the cone or cop I completed a strong pull on the tubelwill cause the resilient;

to yieldjradially andto flex in the opposite direction:;to'* release. the tube sov that it may be removed V omthe spindle and a new b appli g .r s t 1 when the yarn has been completely unwound,---

It will be observed tIlc t my invention pro- 'vides an especially simple and inexpensive device for securing cop-tubes on spindles or skewers and one which is automatic in operation without the use of complicated mechanism. That is to say, there are no springs, levers, dogs or other expansible gripping elements, the resilient disk or washer act ing as the single grippingor securing-means and being proof against wear, derangement Furthermore, in

or getting out of order. operation the device grips and secures the cop-tube to the spindle-by the simple vaction of placing it thereon and when once gripped it is practicallyvproof against accidental re.- moval. 1 At the same time, the tubes maybe released" and removed-from the spindle by simply exerting-a pullthereon without entailingthemanipulation of levers or other i mechanisnrand without requiring any special skillor 'expertness on the part of the oper While have herein shown my improveiment-'asfehibodiedina'preferred form of de-v vice, various modlfications may be made. in

the; structure and arrangement oi its parts without departing from the,spirit or scope of the invention. Therefore, without limiting myself tofthe-exa'ct details of; design and,constructionas herein illustrated and described, I claim:

1.. A copholder for textile apparatus comprising meanson which the cop-tube is. supported 'and airesilient concavo-convex disk I v secure it to the; supportin "-means' adapted to grip the interior of the tube .to while to holding it concentrically t ereof 2. In a cop-holder for, textile machines,

Y the combination of a. spi ndle,sand=avresilient concavo convex cross-section project I ing'radially from the spindle ,to adapt its rim to, frictionally grip the interior of the cop-tube to hold it in, place concentrically of the spindle and to flex to release the tube Wh en'-alp11ll exerted thereon,-

In a cop holder for textile machines,

thehbmbi-ha'tion of a spindle, a threaded sleeve on the spindle provided with an annular flange, a resilient'disk seated against the face of the flange, and a nut screwed onto the sleeve to clamp the disk against the flange. v I a 4. A- cop-holder for textile machines comprisinga spindle having means for rigidly supporting one end of the cop-tube and adisk of resilient material arranged with its peripheral rim engaging the opposite; end of the cop-tube to maintain the latter" in concentric relation with the spindle, said disk susceptible of flexure to cause it to grip the interior of the tube to secure the latter longitudinally of the spindle 'while adapting it to release the tube under a pull thereon to provide for its removal from the spindle,
